Abstract
The invention discloses a kind of preparation method of perfluoroethylene-propylene strainer, preparation process includes melting, drought, braiding, dipping, drying, sizing bonding.The present invention uses and carries out the high-temperature fusion in 5 minutes to exhaustive fluorinated ethylene propylene raw particles at a temperature of 270 372 degree so that the line footpath through drought fabric can reach 0.05 required 0.2mm;By the way that strainer crude product is impregnated via 20% pure water-reducible perfluoroethylene-propylene emulsion, so that since the smaller and mesh of viscosity is not by the particles plug in lotion, the quality of strainer finished product is substantially increased, is had broad application prospects in fields such as oil, chemical industry, food, water process.
Description
Technical field
The present invention relates to a kind of strainer, more particularly to a kind of preparation method of perfluoroethylene-propylene strainer.
Background technology
Perfluoroethylene-propylene material has a series of excellent performances:Heatproof(Minus 85 to 200 degree), resistance to strong acid it is strong
Alkali, resistance to harsh weather so that it has the optimal anti-aging service life in the plastic;High lubrication, non-stick, have solid material minimum
Surface tension without adhering to any material;Nonhazardous, has natural disposition inertia and fire-retardant, can be widely used in oil, changes
The fields such as work, food, water process.It is existing to prepare various strainer products in preparation method and mistake using perfluoroethylene-propylene material
Mainly deposited to following shortcoming in journey:First, in perfluoroethylene-propylene emulsion impregnates strainer crude product technical process, lacking will be poly- complete
The diluted process of fluoro ethyl propene lotion so that due to perfluoroethylene-propylene after perfluoroethylene-propylene emulsion dipping strainer crude product
Lotion viscosity is too big, and the fine particle in perfluoroethylene-propylene emulsion easily blocks the mesh of strainer crude product, so as to largely effect on
The quality of manufactured strainer finished product;Second, the control to melting temperature and melting time is not accurate enough so that through drought
The line footpath of fabric does not reach required requirement.
The content of the invention
Present invention solves the technical problem that the defects of being, overcoming the prior art, there is provided a kind of by being diluted by 20% pure water
Perfluoroethylene-propylene emulsion impregnate so that since the smaller and mesh of viscosity is not by the perfluoroethylene third of the particles plug in lotion
The preparation method of alkene strainer.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals:
A kind of preparation method of perfluoroethylene-propylene strainer, including following preparation process:
A, melt:Exhaustive fluorinated ethylene propylene raw particles are first melted in 270-372 degree;
B, drought:Again by the exhaustive fluorinated ethylene propylene after melting through drought fabric needed for line footpath, obtain
Required perfluoroethylene-propylene filament;
C, weave:Obtained perfluoroethylene-propylene filament is woven into strainer crude product through loom again;
D, impregnate:First take perfluoroethylene-propylene emulsion, then will be poly- complete toward 20% pure water is added in perfluoroethylene-propylene emulsion
Fluoro ethyl propene lotion dilutes, then the strainer crude product obtained in step C is impregnated into the perfluoroethylene after being diluted by 20% pure water
Acrylic acid emulsion;
E, dry:The strainer crude product after being impregnated in D steps is sent into baking oven in 270 degree of temperature and at 1-2 seconds through pressure roller again
It is interior instantaneously to be dried;The present invention passes through experimental verification, and oven temperature is set in 270 degree to the filter after being impregnated in D steps
Net crude product is sent into baking oven through pressure roller instantaneously dried in 1-2 seconds, can reach optimal drying effect;
F, sizing bonding:The strainer crude product after being dried in step E is carried out sizing through special modular system again makes warp
Bonded with weft, obtain strainer finished product.
Preferably, the melting time in step A is no more than 5 minutes.
Preferably, the line footpath in step B is 0.05-0.2mm.
Preferably, screen mesh number is 20-100 mesh.
The present invention has significant technique effect as a result of above technical scheme:Using right at a temperature of 270-372 degree
Exhaustive fluorinated ethylene propylene raw particles carry out the high-temperature fusion in 5 minutes so that the line footpath through drought fabric can reach
Required 0.05-0.2mm;By the way that strainer crude product is impregnated via 20% pure water-reducible perfluoroethylene-propylene emulsion so that by
In the smaller and mesh of viscosity not by the particles plug in lotion, the quality of strainer finished product is substantially increased, in oil, chemical industry, food
The fields such as product, water process have broad application prospects.
Embodiment
